The turbine is thus blocked by way of the linings between the piston and cover, and permits rigid through drive with no slip or reduced slip if controlled to the mechanical stage of the transaxle. The encoding is such that malfunctions in the connecting lead are identified. The transaxle control module TCM is an electronic 4ph16 which monitors inputs to control various transaxle functions including shift quality and transaxle sensors, switches, and components to process for use within its’ control program.

Also, the TCM performs the and shifts earlier to help reduce fluid heat generation. The advantages of this dynamic pressure equalization are:.

ZF 4HP16 transmission – Wikipedia

The purpose of the shift elements is to perform shifts under load without 4hp116 tractive flow being interrupted. The stator, which bears against the housing via the freewheel, is then rotating freely in the oil flow and the freewheel is 4hpp16. This oil flow meets the turbine wheel, where is direction of flow is deflected. In other words, front ring gear is permanently linked to rear planet carrier, front planet carrier is linked to rear ring gear.

An air gap of 1. Disconnect the negative battery cable before removing or installing any electrical unit or when a tool or equipment could easily come in contact with exposed electrical terminals. Calculated temperature is a factor to determine at the shift time and shift delay time.

The converter lock-up clutch is a device, which eliminates converter slip and thus helps to improve fuel consumption. The space between pressure also 4np16 up. The ratio between turbine torque and torque is referred to as torque multiplication.

Vehicle speed information is used by the TCM to control shift timing, line pressure, and LUC lock-up clutch apply and release. The selector lever position is transmitted to the 4hp6 in encoded form along 4 lines.

The transaxle electrical connector is a very important part of the transaxle operating system. The TFT sensor is a positive temperature coefficient thermistor temperature sensitive resistor that provides information to the TCM regarding transaxle fluid temperature.

Selector Lever Line L1. Input Speed Sensor Ground. The parking lock pawl in the parking lock gear, which is welded onto the 4hp166 shaft of the transaxle. Higher vehicle speeds induce a higher frequency and voltage measurement at the sensor.

The space between the baffle 4yp16 and piston is filled with unpressurised oil.

Shifting between individual gears takes place by means of overlapping clutch engagement and release. A planetary gear train establishes the mechanical gear ratios. H4p16 the static pressure is relieved, the cup spring is able to force the piston back into its original position.

It protects the vehicle mechanically against rolling away. When the oil pressure drops, the cup spring acting on the piston presses the piston back into its initial position. The ignition must also be in LOCK unless otherwise noted. The pressurized oil reaches the space between the cylinder and piston, as a result of which the discs are h4p16. The previous control principle for converter lock-up clutch operation has been replaced by a controlling function on the 4 HP Push the connector straight down into the transaxle without twisting or angling the mating parts.

The parking lock is actuated via the selector lever when in position P. The fluid pump fulfills the following functions:. The valve reduces the system pressure with which the downstream solenoid valves and electrical pressure regulating valves are charged. The result is optimum shift quality. The electronic-hydraulic control makes controlled power shifts and various shift programs possible. The EDS require a constant input pressure. To reinstall the external wiring connector, first orient the pins by lining up arrows on each half of the connector.

This information is also uses to calculate the appropriate operating gear ratios and LOC slippage.

The oil pressure passes from the turbine chamber to the lock-up clutch piston and presses it against the converter’s cover. The TCM sends a 5volt-reference signal to the temperature sensor and measures the voltage rise in the electrical circuit. The output speed sensor mounts in the case at the speed sensor rotor, which is pressed onto the spur gear. The internal electrical resistance of the sensor varies in relation to the operating temperature of the transaxle fluid see chart.

Input Speed Sensor. The ZF 4HP 16 automatic transaxle is equipped with a one sun gear, 4 planetary gears, planetary carrier, ring gear. The input speed sensor mounts onto piston B that is inside of valve body.

The pump sucks the fluid through a filter and delivers it to the main pressure regulator valve of the control system. Each gears are located one directly behind the other and are linked together. The special feature of this transaxle is that it operates without freewheels. Output Speed Sensor. When open conversion rangethe oil pressure behind the converter lock-up clutch piston and in the turbine zone is equal.
